How does this skill handle user cancellation in the terminal?

It enforces the use of p.isCancel() after every prompt and ensures SIGINT (Ctrl+C) is handled gracefully using standardized, named exit codes.

Can I build multi-step wizards with this skill?

Yes, it includes specific patterns for wizard state machines that support complex flows, including back navigation and history tracking.

What libraries are required to use these patterns?

These patterns are designed for Node.js projects using Commander.js for command parsing and @clack/prompts for the interactive terminal interface.

How does it manage configuration precedence?

It implements a clear hierarchy where CLI flags take precedence over environment variables, followed by project-level config, global config, and finally hardcoded defaults.

Why does the skill require using parseAsync()?

The use of parseAsync() is critical for Node.js CLI tools to properly propagate and catch errors from asynchronous action handlers, preventing silent failures.
